This study investigated whether serious adverse events (SAEs) during antituberculosis therapy occur more frequently in HIV co-infected patients in a South African population. A retrospective analysis examined incidences of hepatotoxicity, peripheral neuropathy, severe arthralgia, persistent vomiting and severe rash in 400 patients treated for tuberculosis in a community clinic. A total of 141 patients were co-infected with HIV, among whom only 16.3% were receiving antiretrovirals. Details of SAEs were ascertainable in 331/400 patients, and occurred in 26.7% of HIV-infected and 13.3% of HIV-uninfected individuals (P = 0.003). The excess was attributable to increased peripheral neuropathy (8.3% and 1.9%, respectively, P = 0.009) and persistent vomiting (13.3% and 3.3%, P = 0.001). SAE occurrence was not related to antiretroviral use, although median CD4 counts were lower in those experiencing side-effects (130 and 259 cells/microL, P = 0.008). The treatment completion did not differ significantly between the two groups (76.6% and 84.2%, P = 0.08).

Lymphocyte numbers in bronchoalveolar lavage fluid varied widely in localised pulmonary and miliary tuberculosis but were highest in lavage fluid from patients with miliary tuberculosis. This was due to an increase in CD8 lymphocytes, which were also increased in the blood. Lymphocyte numbers bore no relation to nutrition, symptom duration, or radiographic profusion scores. In miliary tuberculosis the time taken for the chest radiograph to clear (mean (SD) (7 8) We have compared lymphocyte numbers and subsets in the lungs, blood and, where possible, the pleura of patients with different forms of pulmonary tuberculosis (local, miliary and pleural) and assessed the serial changes that occurred during successful treatment.
